A liquid crystal display includes source lines and gate lines, pixel electrodes, switching elements, a source driver, a gate driver, and a failure inspection circuit. The source lines and the gate lines are disposed in a lattice form. The pixel electrode is disposed in a pixel region defined by the source line and the gate line. The switching element is disposed corresponding to the pixel electrode. The source driver drives the source lines. The gate driver drives the gate lines. The failure inspection circuit is connected to the source lines or the gate lines, and performs inspection of the source lines or the gate lines. The failure inspection circuit includes monitor input signal lines, monitor output signal lines, a determination circuit that detects voltage levels of output signals from the monitor output signal lines, and an expected value comparison circuit that compares outputs from the determination circuit with expected values.
